Comparing plant growth regulators: Anuew, Primo Maxx and an experimental on a USGA putting green
Year: 2021
Type: report
Abstract: Applying plant growth regulators to economically significant turf on golf courses to control height, reduce frequency of mowing operations, and enhance playing surface consistency is a common industry practice. This study compared Anuew (prohexadione-calcium), Primo Maxx (trinexapac-ethyl) and experimental NAI-20026 (trinexepac-ethyl) on turfgrass growth and quality parameters on a greens-height stand of creeping bentgrass. On many occasions throughout the experiment, PGR treatments significantly reduced turfgrass growth when compared to the untreated control and improved turfgrass quality and colour ratings. Anuew 5.6 had significantly higher NDVI readings than the untreated control on three occasions throughout the experiment. NufTE (experimental NAI-20026) performed similarly to Primo on both the 300 GDD and 4-week application schedules and often were ranked the same for many parameters throughout the experiment. No stress symptoms (yellowing, etiolation) were observed on the putting green turf in response to PGR application during hot/dry weather at any point during the experiment.
